1,2-Dimethylethylenediamine (DMEDA) is the organic compound with the formula (CH3NH)2C2H4. It is a colorless liquid with a fishy odor. It features two secondary amine functional groups.
Reactions
DMEDA is used as a chelating diamine for the preparation of metal complexes, some of which function as homogeneous catalysts.[1][2]
The compound is used as a precursor to imidazolidines by condensation with ketones or with aldehydes:
- RR'CO + C2H4(CH3NH)2 → C2H4(CH3N)2CRR' + H2O
